Mt. Tres Marias, with three peaks, is the highest mountain on Biliran island and part of the Biliran volcanic complex; Mt. Naliwatan, seen from its summit, is a separate peak. The climb passes many waterfalls, among them Sampawan, Ulan-Ulan, Recoletos and Nomads' falls, and above 1,200 m a mossy forest holds pitcher plants.
